The present invention relates to the art of making or producing metal wool bodies, more particularly metal wool pads.

In the producing of metal are used for cleansing and scouring purposes, there has existed a disadva tage in that the fibres going to make up the pad are easily separated or pull is effected, or imposed upon the pad. This is particularly so when the fibres are short and not so interlaced or interwoven as to hold together.

To avoid such a disadvantage, posed to use fibres of greater length and to wind 9. sheet orribbon or web of such cylindrical form and then flatten the cylinder to produce a sort of square or rectangular pad. Such a pad easily tears apart when a pull is efiected in the axial direction of the cylinder or the pad made from it The disposition of the fibres is only in one direction.

. The present invention comprehends the winding into a body oi! any desired shape of a plurality or, long metal fibres or filaments of inwool pads such as definite length continuously in web loops in difierent directions so that the disposition of all or fibres will be in more than one direc- A'ny pull on the mass of that body in more than one direction will be resisted by the fibres disposed in such direction and hence it is impossible normally to tear the fibres apart. Even when the body is flattened into the form of a disposition or arrangement of the fibres to extend in more than one direction across the pad, irrespective of the shape or the .pad, offers resistance in-more than one direction or pull that might or would ordinarily tear the fibres or filaments apart in the older forms or pads.

The invention also comprehends a novel metal wool body or pad of the kind described above. v

Other objects, capabilities, feaprocess steps and the like are comprehended by the invention as will later appear and as are inherently possessed thereby.

arranged in sheet or ribbon form;

Fig. 3 is a view oi a completed wound body:

Fig. 4 is a top plan view of a pad made from the body shown in Fig. 3; and,

Fig. 5 is a side view of such a pad.

Referring more in detail to the drawing and for the purpose of illustrating the invention, a plurality of long metal fibres or filaments l indefinite length as desired are arranged in a more or less parallel relation so as to form a sheet or ribbon or web 2. An object of this 5 invention is to so wind the ribbon or web that there will be a crossing and/or recrossing of the fibres or filaments the parts previously wound, whereby the fibres or filaments in the wound mass or body will be ar- 10 ranged in more than one As for example, the winding may be started by portion'3 to dispose the fibres at an angle or portion 4 of the ribbon, ner portion 5 likewise across or the fibre portion 4. Then the end portion 6 may then be turned to dispose the fibres across the previously turned portions 3 and 5, and so forth until a suitable core just what shape this core may takewhether round or otherwise. Then the ribbon or web is wound on the core so as to dispose a portion such as portion 1' (Fig. 2) in one direction of winding. As the winding-progresses the ribbon 25 or web is caused to extend across or at an angle to the previously wound portion, such as portion 8, shown in Fig. 2, and thence further winding brings such a portion 9 across the portion 8, etc. While the showing in the drawing for purposes of 30 illustration is that in the form of a ball it is to be understood that any shape of the body may be produced. I

To produce the pad as shown in Figs. 4 and 5 it is preferable to compress .or flatten the body 5 shown in Fig. 3., This does not disturb the relation of the fibres. As will be seen in Figs. 4 and 5 the fibres or filaments run across the pad and also around the edge portions of the pad in more than one direction, the fibres of a portion cross- 40 ing the fibres of another portion so that they are interlaced or interwoven and so disposed that any pull imposed on the pad in more than one direction will be opposed or resisted by the fibres disposed in that direction thuspreventing the 45 tearing apart of the fibres or filaments, especially those disposed transversely to'the fibres or fila- .ments subjected to the pull.

.Such a pad is durable, has a longli-fe, and will' be more efiicient in its use, especially when used 50 with soap whether impregnated or otherwise as is formed.
